It's the same motor I had that broke a camshaft in half @ 6k miles and a blown hg 2k miles later. The block was rehoned, heads resurfaced, one piston was replaced, all four pistons had the skirts coated, new rings, one rod had the small end bushing "fixed", the crank was machined for undersize main bearings, and that's about it besides new headstuds, gaskets, bearings, t-belt/tensioner, and little things. The heads were in great shape after all the problems and I was very happy about that.
My built motor was 100% destroyed a couple weeks and a couple hundred miles after I posted this. Three valves dropped into cyl #4. All the rod bearings had excessive wear on the outside edges of the shell, while the middle was like new... and the sides of the rods had wear from hitting the crank. Ron@raw1 turned into a dick, blamed the installer/tuner, and completely forgot about my motor at one point while he had it apart. When I got the parts back we found mega side clearence on the rods, but that's not why the valves dropped.

Why are these motors such a gamble?

There are people in this thread who have had failure after the motor was built by a reputable builder...others have had theirs slapped together in their home garage and lasted 40k.

What's up?

A tad over 50K on my cobb block w/ coated pistons and rod bearings.
Burns oil now.
Compression is low but even.
Daily driven.
I might re-ring it or just replace it with a new built setup in the next 10-20K.

It's over 2 years old so I can't remember the exact clearances.

It's just a basic build; Hone, stock bore CP's 8.2:1 CR, Manley I Beams, cosworth race bearings, ARP studs, and stock headgaskets.

Same here. My older COBB block has taken a beating. Whoever built their motors apparently did a pretty good job.

These are complicated motors, theres a lot to go wrong, but if its built correctly, the tune on break in is 99% of it from my experience.

I just rolled 3100. 2000 miles of those miles were very hard. I have no idea how long she will last, but quite frankly im surprised it made it this far.

I want 60k, that my goal. What sux is I blew the trans in my kia beater.... Those 3100 were put on the motor in the last month........

bought a stage 3 motor from axis. bad motor right off the get go. Burning 1 quart every 80 miles. yes 80 miles. compression test 100 across the board and leakdowns of 25ish and 2 cylinder and 40 ish on the others.Tried to get warranty work. John at axis blammed it on the install. Said if i wanted to take the motor out and pay for that, then pay to ship it, he would fix it at cost....LOL...what a joke!!! In my opinion go with cosworth and be done with it!! Heard nothing but good thing with cosworth and they last longer then other blocks because of tighter clearances.

Damn, that sucks.

However, the lesson I see from that is to have the motor built, installed, and tuned at the same shop. That way the builder and tuner and installer can't all blame each other and walk away if **** happens. If that same shop installed a Cosworth engine and you ended up burning oil and making crap compression, you'd be in exactly the same situation.

about 1k for the last 2 mos on my built longblock. p&l is still trying to figure out why an apt35r (stock loc) is only making around 330whp and falling flat on its face around 5500rpm.

That really sucks, sorry to hear that i hate hearing about things like this.. People spend all this money to get things done THE RIGHT WAY and most shops nowadays are just after your money and how fast they can get it done, not worrying about making sure its done and measured correctly.. Again sorry to hear that, he lost my business.. I was DEAD SET on going with a block from Ron after all the good things i had heard, and called and talked to him even and he seemed like a good guy, but lately ive been reading about nothing but failed motors by him, its not all done by the same tuner and this is just too much IMO for it to be coincidence so i went with a local shop instead and they got it together nice a quick, not in the car yet though so we'll see how she does when it gets some boost thrown at it.. Its Closed deck with full forgd internals, race bearings, etc. so hopefully it holds up good..

Not if you read the poll question as "how many miles on your built motor so far?"

It might be interesting to do a different poll on a different question: "how many miles on your built motor before it popped?"
